Abstract

The time slots of M-ary pulse-position-modulation (PPM) can be replaced by M optical CDMA codes: Code/Pulse-Position-Swapping (C/PPS) or Code-Shift-Keying (CSK). Features of C/PPS are that it: (1) retains the intensity-modulation/ direct-detection (IM/DD) and multiple-bits-per-symbol features of PPM; (2) supports multiple access communications; (3) supports bandwidth-on-demand; (4) supports tailoring quality of service; (5) translates the received symbol to its corresponding bit sequence without using look-up-tables (LUTs)); (6) and has a common electronic bandwidth for all data rates. In this paper we describe the design of C/PPS encoders and decoders based on the specific example of 4x4 fast frequency hopping (FFH) sonar codes.
